The capillary rise against 'gravity towards Earth' is due to gravitational and electromagnetic forces between atoms of the solid surface and the atoms on the liquid surface. The mobile molecules of water just gets packed inside. Actually, it is the difference in 'force felt' between the inside and outside of the capillary, that causes the rise. So removing gravity may not affect.
